How to restore a MySQL database

Step 1: Determine the backup to restore

Restoring the database from backup is the most common method to restore a MySQL database. Determine the location and time of the backup to be restored.

The MySQL service must be stopped before starting the recovery process. Run the following command from the command line:

You can use the mysqldump command to restore the database from the backup file. The command syntax is as follows:

<code>mysqldump --user=[用户名] --password=[密码] [数据库名] < [备份文件路径]</code>

After restoring the backup, you need to import the restored database into MySQL. Use the following command:

<code>mysql --user=[用户名] --password=[密码] [数据库名] < [恢复后的数据库文件]</code>

Step 5: Refresh Permissions

After restoring the database, you need to refresh the permissions to ensure that the database user has the correct access rights. Run the following command:

<code>FLUSH PRIVILEGES;</code>

Step 6: Start the MySQL service

After completing the recovery process, you can start the MySQL service. Run the following command from the command line:

<code>sudo systemctl start mysql</code>
